Bloomberg later put his estimated one-day gain at $89 billion. That was a mark-to-market estimate—not cash paid to Ellison—and the apparent record depended on the share-price snapshot and wealth tracker used.
What happened to Oracle stock on September 10, 2025?
Oracle closed at $328.33, up 36% for the day, according to the Associated Press. Forbes Australia reported that shares rose 41% intraday, describing it as Oracle’s biggest intraday gain since a 43% rise in December 1992. The 41% figure refers to the session’s high, not the closing gain.
The difference matters: a stock can reach a higher price during trading and then retreat before the closing bell. Forbes Australia said Oracle’s market capitalization climbed from $678.4 billion at Tuesday’s close to around $957 billion intraday Wednesday. Those figures describe market value, not money paid to Oracle or its shareholders.
Why did Ellison’s estimated wealth rise so much?
Ellison’s fortune is closely tied to Oracle because he owns a substantial portion of its shares. The AP described his stake as about 40%; Forbes Australia put it at roughly 41%. When Oracle’s share price surged, the estimated market value of that stake rose with it.
#1 Best Overall
Bloomberg’s retrospective reported an estimated $89 billion increase in Ellison’s wealth. That number is an estimate derived chiefly from repricing his holdings; it does not mean he sold shares or received $89 billion in cash. A large stake can generate an enormous paper gain in a single session when the underlying stock makes an unusually large move.
What drove the Oracle rally?
Cloud-infrastructure forecasts
Oracle’s upbeat outlook for cloud infrastructure was a key catalyst. As reported by Forbes Australia, Oracle forecast cloud-infrastructure revenue of $18 billion in fiscal 2026 and $32 billion in fiscal 2027, followed by $73 billion, $114 billion, and $144 billion over the next three years. These are forward-looking company forecasts reported by Forbes Australia, not realized revenue.

A sharp rise in contracted future business
Forbes Australia reported that Oracle’s remaining performance obligations rose 359% to $455 billion. Remaining performance obligations represent contracted revenue that has not yet been recognized; they signal future work under contract, but do not mean the full amount is current-period sales or guaranteed profit.
Quarterly results were a separate part of the picture
The same Forbes Australia report said Oracle’s first-quarter revenue was $14.9 billion, below the $15 billion analyst estimate, and earnings per share were $1.47 versus an estimate of $1.48, citing FactSet. The share-price reaction therefore reflected expectations about future cloud growth and contracted demand, not a claim that every reported quarterly figure beat forecasts. AP reported Ellison’s remark on the earnings call: “AI Changes Everything.” It captures the company’s AI-focused pitch, but is not evidence that its forecasts will necessarily be met.

Did Ellison pass Elon Musk as the world’s richest person?
Briefly, some live rankings placed Ellison above Musk during the trading day. But the reported estimates differ by tracker and timestamp:
| Source and timing | Ellison estimate | Musk estimate | What it shows |
|---|---|---|---|
| Forbes Australia, earlier intraday estimates on September 10, 2025 | $404.6 billion | $436.3 billion | These estimates did not put Ellison ahead of Musk. |
| Associated Press, end of day on September 10, 2025 | $383.2 billion | $384.2 billion | Musk was narrowly ahead by the close. |
The figures are not a reconciled set: they came from different estimators and snapshots. The AP said Musk had regained the top position by the close. The momentary ranking should be understood as a historical market event, not a statement about who is richest now; later coverage documented further large changes in Oracle’s share price and Ellison’s estimated wealth.

How to read the headline numbers
- Check the price measure: Oracle was up 36% at the close, while the 41% figure was intraday.
- Check the timestamp: a wealth estimate taken near a stock’s high can differ materially from an end-of-day estimate.
- Check the estimator: billionaire rankings use estimates and methods that can differ; the cited figures are not directly interchangeable.
- Separate current results from forecasts: quarterly revenue and EPS were slightly below analyst estimates even as cloud guidance and remaining performance obligations supported optimism about future growth.
